About Folder Size Explorer

Folder Size Explorer is a free Windows Explorer extension that will calculate folder sizes. Microsoft's Windows Explorer does not calculate folder sizes automatically. You have to right-click a folder and select "Properties" to calculate its size. While this may be acceptable for a single folder it is very inconvenient if you are trying to determine which folders on your hard drive are taking up the largest disk space.

FSE calculates folder sizes and allows you to see which directories are using up the most disk space simultaneously at a glance. A convenient context menu in Windows Explorer - "Scan with Folder Size" makes it possible to list all folder sizes at any time. The directory analysis tool does not make modifications to the system or Windows Explorer therefore it is absolutely safe. This guarantees that it will not slow-down your system or cause any issues with other applications.

It can save file and folder sizes lists to CSV or XML files that can be viewed in Excel or Notepad. The tool has native 32 and 64-bit versions which guarantees that it will run as fast as possible on your operating system. The free disk analyzer supports Windows 10, 7, 8.1, 8, Vista, XP, 2008, 2012 and 2016.
